3.25 LCD-TFT controller
The LCD-TFT display controller provides a 24-bit parallel digital RGB (Red, Green, Blue)
and delivers all signals to interface directly to a broad range of LCD and TFT panels up to
XGA (1024x768) resolution with the following features:
• 2 displa
y layers with dedicated FIFO (64x32-bit)
• Color Look-Up table (CLUT) up to 256 colors (256x24-bit) per layer
• Up to 8 input color formats selectable per layer
• Flexible blending between two layers using alpha value (per pixel or constant)
• Flexible programmable parameters for each layer
• Color keying (transparency color)
• Up to 4 programmable interrupt events
• AXI master interface with burst of 16 words
3.26 JPEG Codec (JPEG)
The JPEG Codec can encode and decode a JPEG stream as defined in the ISO/IEC 10918-
1 specification. It provides an fast and simple hardware compressor and decompressor of
JPEG images with full management of JPEG headers.
The JPEG codec main features are as follows:
• 8-
bit/channel pixel depths
• Single clock per pixel encoding and decoding
• Support for JPEG header generation and parsing
• Up to four programmable quantization tables
• Fully programmable Huffman tables (two AC and two DC)
• Fully programmable minimum coded unit (MCU)
• Encode/decode support (non simultaneous)
• Single clock Huffman coding and decoding
• Two-channel interface: Pixel/Compress In, Pixel/Compressed Out
• Support for single greyscale component
• Ability to enable/disable header processing
• Fully synchronous design
• Configuration for high-speed decode mode
3.27 Random number generator (RNG)
All devices embed an RNG that delivers 32-bit random numbers generated by an integrated
analog circuit.
3.28 Timers and watchdogs
The devices include one high-resolution timer, two advanced-control timers, ten general-
purpose timers, two basic timers, five low-power timers, two watchdogs and a SysTick timer.
